IMPROVEMENT IN MACHINES FOR CROZING- STA'V'ES.

The Schedule referred to in these Letters Patent and'making part of the same.

Figure 1 represents a vertical longitudinal section of a machine embodying my invention.

Figure 2 is a plan view of the same.

The object of my invention is to provide a machine for ohamfering, crozing, and cutting off, to a uniform length, staves for barrels, casks, 620., all in one opera tion; and the-invention consists in the employment of a sliding frame, operated by a weight, in connection with two circular disks, provided on their circumference with pins, or studs, which serve to take up and carry forward the staves during the cutting-operation,

the staves being held upon the saiddisks by means of springs or elastic pressure-bars. while being cut, and then are allowed to drop off from the said disks, as the latter rotatzand when the cutting-operation is finished.

Referring to thedrawings A A represent-the frame, which may be of any suitable size or shape.

B is an incline feed-board, upon which the staves are placed, to be fed to the disks or wheels 0 0.

Upon the feed-board B is arranged a sliding frame, D, which may be attached to the same by means of a tongue and groove.

A forward motion toward the disks 0 O is imparted to the frame D by means of a cord and weight, g, the end being attached to the-under side of the frame D, and passing over a pulley, c, as shown.

C 0 represent two disk-wheels, mounted upon a horizontal shaft, j, having its bearings in the inner portions 7 r of the frame.

Upon one end of the shaft j is a worm-gear, which engages with an endless screw on a vertical shaft, m,

to which motion is imparted by means of a band from any moving parts of the machine.

On the periphery of the disk-wheels O G, is a series of projections or pins, so arranged as totake up the staves as they are fed from the inclined table B, and

carry them forward, to be acted upon by the cutters,

after which they drop from the machine.

Over each disk-wheel is arranged a spring or pressure-bar, G, attached at one end to the rear of theframe,

and extending to the front portion of the feediframe D, for the purpose of retaining the staves upon the disk-wheels, as they are brought under the action of the cutters.

Upon each side of the upper rear portion of the frame are arranged two shafts or spindles q q, on the inner ends of which are cutters i 7 so formed as to out the recess in, and chamfer the inner ends of the staves.

h h are saws, for sawing oh the staves to a uniform length.

The cutters and saws may be adjusted further from or nearer to each other, so as to cut and chamfer staves of difl'erent sizes. 7

The staves being placed upon the inclined feed-board B, the frame D is drawn back, and placedagainst the rearmost stave.

The weight 9 will serve to draw the frame D down, and thus feed the staves to the disk-wheels O O, by which the staves are successively carried forward, and subjected to the operation of the saws and cutters, and then pass over to the rear of the machine, and drop down from the same.

- That I claim as my invention, and desire to secure by Letters Patent, is-

- The inclined feed-table B and weighted feed-frame D, in combination with the disk-wheels O O, feed-pins, and retaining-springs G G, operating in the manner and for the purpose substantially as described.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.

HARRISON ELLIOTT.
